Newbie's first attempt
Pic Dude email (remove spam text)
First, slap yourself on the wrist for use of 'tris'. I'll let
it slide this time. :-) I copied your code into MPLAB and
simulated it successfully. So that's okay. The problem must
be with the circuit. Can you email that or ascii-draw it here?
Few things I can think of:
- Some programmers will not give you feedback if the programming
fails. Test this by building one of the LED flashers from
the piclist site, etc. IE: something *known* to work.
- Is MCLR connected to +ve?
- You're resetting your delays with '0F' which is 16. With 2
counters, you have a delay of 256 loop cycles. At 4Mhz, each
instruction is 1 micro-second, so that's not much of a
delay. Change those to 'FF' or so for now.
Either way, even though you say that the circuit is correct,
there may be something that a fresh and more experienced pair
of eyes may pick up.
